Comparison of the Efficacy of Rhomboid Intercostal Block and Erector Spinal Plane Block on Myofascial Pain Syndrome

Comparison of the Efficacy of Ultrasound Guided Rhomboid Intercostal Block and Erector Spinal Plane Block on Lower Cervical and Interscapular Myofascial Pain Syndrome

The investigators evaluate the effect of Ultrasound guided Rhomboid Intercostal Block and Erector Spinal Plane Block on lower cervical and inter scapular Myofascial Pain

Myofascial pain syndrome (MPS) is the most common cause of musculoskeletal pain and its prevalence in the population is reported to be 21-30%. In this study, the investigators compare the effect of two regional anesthesia block techniques with the ultrasound guidance.
